I think it depends on what you liek to do... if you enjoy the club scene and dancing, then its GREAT - you only pay one cover and get to visit several clubs at the same time.
There are 3 (is that right, just 3?) that aren't specifically dance clubs... Comedy, Adventurers, and Jazz. Comedy usually has a line to get in for later shows, Adventurers wasn't TOO crowded, and the Jazz isnt usually crowded depending upon whos playing.
I have spent the most time at the Jazz club, and I love the environment there. Quiet, dark, comfy, and entertaining.
Totally depends on your personality and what you enjoy =)
